You need to hire more flight crews. My suggestion to you is to hire back up crews. My sons flight was cancelled and I had a panic attack behind the wheel of my car because I have both generalized and social anxiety disorder. Because you overwork the crews you have and consequently had no crew to fly the plane and I had to drive on the freeway by myself and that is one of my biggest anxiety triggers and then almost ran out of gas circling the airport trying to figure out where to pick up my son and almost got in an accident and all this on no sleep because my sons flight was supposed to leave at 12:25 A.M and I had to come back at 1:00 A.M and from where I live it takes me 2 hours to get to the airport because I wont drive the freeway unless there is absolutely no other option available because it triggers my anxiety and in this case there wasn't because everyone else was already asleep. Now I'm not asking you to personally cater to my son or me. I'm telling you you are putting peoples lives at risk by overworking your crews.
